Does anyone have any examples of what they would use this for? I can’t think of anything I would do with it, but I’m not terribly creative…
A rough analogy is what if you were running an small business. You would give the IT jobs to the 'IT guy'. The 'HR' stuff to the 'HR guy'. The accounting stuff to the 'Numbers gal' . and the communications/media gal would arrange the press releases , ad buys, and general communication. You 'hire' folks to do work based on their skill set that better than the other folks in the group. Everybody is not completely interchangeable.
The notion here is that different "Frontier' models have increasingly specialized skill sets. That runs very counter to how some folks are treating these models. Some are on the path of only giving everything to the one all knowing , all power model that does everything better than anybody. The latter set of folks don't want to buy this.
On the other side, it isn't all that mainstream for a generic users to have paid for AI chat subscriptions to 2-4 different model services vendors. ( buy account at Claude , OpenAI , and Perplexity). If don't have multiple accounts and not paying Perplexity for max model then this app actually doesn't work.
Perplexity's model (also in the cloud) orchestrates dispatching the work to various models. Each one of these models may have different upload/download points. Different intermediate files. Settings. etc. The Mini is basically a nexus point between a wide variety of vendors. ( and could keep some crticial files that are input/output local and out of the long term storage in the cloud. )
Over time I suspect some local models make take some of the workload. For example, perhaps tasks that deal with requesting local Mac app data or general file access go through Apple's AI agent that users trust more.
OpenAI dumping Sora is somewhat illustrative that the idea of the 'all knowing all seeing " model is dubious at least and possibly just smoke and a myth. Making the models bigger and bigger at some point likely is going to hit a wall. So if stop trying to be an expert at EVERYTHING then perhaps better to become differentially better at specific skills.
And if go back to context where have different workers for different jobs. There is common vocabulary that is used to coordinate with each other but each individual knows words and concepts that the others don't.
However, as others have talked about, the security model and protections here are somewhat vague. Also likely have 'holes' if this was all whipped together in a great hurry. ( e.g, AI tool whipped up most of it and no one has throughly testing it. ) All the orchestratin work is going up to Perplexity's clound and back down again. (possibly watch how all the tools are composed and likely has access to all of the shared files repository. )
